FATMAP difficulty grade
This is the ultra-popular summer float section of the Boise River, from the put-in at Barber Park to the takeout at Ann Morrison Park.
The greenbelt more or less follows the river between both parks, through a mix of urban and more natural settings.
You can park at Ann Morrison, pack your inflatable and bike to Barber, then float back to the car! During the rest of the year when it's too cold to float, this remains a nice ride beside the river and Boise State campus.
